Prospex Alpinist

The Seiko Alpinist remains a cornerstone of the tool-watch canon, having evolved from its 1959 mountaineering roots into a quintessential modern daily driver. This SPB507 example is presented in excellent condition, featuring a 39.5mm stainless steel case, the reliable Caliber 6R55 movement, and its original box and papers. It is finished with a rich green dial and paired with the factory-supplied brown leather strap. This is a refined, utilitarian companion that balances heritage design with the mechanical substance required by today's enthusiast.
